HENRY A. OWEN, OF WHITINSVILLE, MASSACHUSETTS, ASSIGNOR TO THE WHITINMACHINE WORKS, OF SAME PLACE.

.SPlNDLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 528,020. dated October23, 1894.

Application filed May 10, 1894;

To all whom it may concern.-

Be it known that I, HENRY A. OWEN, of Whitinsville,in the county ofWorcester and State of Massachusetts, have invented certain new anduseful Improvements in Spindle- Supports; and I hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, forming part of thisspecification.

This invention relates to improvements in supports for spindles in whichthe spindle bolster is furnished with a laterally-extendingoil-reservoir having a hollow post or well at its outer end by means ofwhich oil is introducedinto the oil-reservoir anda column of oil abovethe reservoir may be secured.

The object of the invention is to provide the spindle support with acombined dofierguard and oil-well cover which will be simple inconstruction and operation and more durable than those heretoforeconstructed.

The invention consists in the combination with a laterally-movable post,of a dofierguard and oil-well cover mounted at the upper end thereof.

The invention also consists in the peculiar construction of thebolster-case and the combination therewith of the novel means forsupporting-and operating the post on which the dofier guard andoil-wellcover is mounted.

The invention likewise consists in such other novel features ofconstruction and combination of parts as may hereinafter be more fullydescribed and pointed out in the claims.

Figure 1 represents an elevation of parts of the spindle and the bolstersecured in the bolster-rail showing the improved doiferguard andoil-well cover. Fig. 2 represents a plan view of the spindle, thebolster, and the dolfer-guard and oil-well cover. Fig.3 represents anelevation of the bolster-tube and oil-well. Fig. 1 represents a bottomView of the same. Fig. 5 represents a perspective view of the supportfor the doffer-guard and oil-well cover removed from the bolster.

Similarnumbers of reference designate corresponding parts throughout.

In the drawings 8 indicates the bolster tube so of the ordinaryconstruction having the flange or collar 9 which has heretofore restedSerial no. 510,717. (No model.)

on the bolster-rail 10. From this flange extends the oil-reservoir 11connected withthe interior of the holster-tube and having at its outerend the hollow post or well 12 through which oil is introduced into theoil-well and by which a column of oil may be maintained above thereservoir. In the bolster-tube is journaled, in any suitable manner, aspindle 13 having the whirl 1 1 by means of which the 6o spindle isdriven;

In my construction I raise the bolster-tube and its flange 9sufficiently above the bolsterrail to allow the placing of theeccentric-cam 15 between the bolster-rail and the flange. 6 This cam maybe made in part with the bolster-tube, or be secured thereto or to therail, being so arranged that its point of farthest throw from the centerof the bolster is diametrically opposite to the location of theoilreservoir, its point of shortest throw being adjacent to theoil-well. Surrounding this cam 15 is a cam-ring 16 having its bore 17located off the center. On the widest portion 16 ofthe wall thereof Imount the post 18 I having at its lower portiona shoulder 19 which inthe normal position bears on the edge of the flange 9, and at the upperend of the post, formed in part therewith or rigidly secured thereto, Ilocate the inwardly-ex- 8o tending doffer-guard 20 and the oil-Wellcover 21, these being supported by the post at a height slightly abovethe upper end of the oilwell 12 and above the spindle whirl.

When the spindle is running in its normal condition the dotter-guard'and oil-well cover are located as represented in solid lines, the coverclosing the oil-well and the dolTer-guard extending over the spindlewhirl and preventing its undue lifting in doffing or otherwise. When itbecomes necessary to add a supply of oil to that in the reservoir, thepost 18 is moved laterally a short distance by rotating the ring 16 touncover the oil-well without opening the passage for the whirl, the oilis 5 introduced and the parts replaced. When it is desired to remove thespindle from the bolster, the ring 16 is rotated until the post 18 isbrought to the position indicated in dotted lines in Fig. 2, when theeccentric-cam 15 in conjunction with the cam-ring 16 will have causedthe post 18 to move suficiently away from the center of the bolstertoopen a free passage for the spindle whirl.

Having thus described my invention, I

claim as new and desire to secure by Letters 5 Patent 1. In a spindlesupport, the combination with a bolster-tubefurnished with alaterallyextending oil-reservoir having an upwardlyextending oil-well,of a post extending in a plane parallel to the axis of the b0lster,a

support on which the post is secured, mounted eccentric-ally to the saidbolster-tube and embracing it, andan oil-well cover carried on the upperend of said post.

2. In a spindle-support, the combination with a bolster-tubehavingalateral oil-reservoir furnished with an-- upwardly-extending0il-We1l,of an eccentric cam surrounding the bolster-tube, a ringrotatable on said'cam, and

a vertical post rigidly secured to said ring and having a dotfer-guardand oil-well cover atits upper end.

3. The combination with a bolster-tube 8 having the flange 9, theoil-reservoir 11 and the oil-well 12, and the cam 15 surroundingthebolster-tube, of the ring 16 rotatable on movable base having a postmounted thereon, adevice for guarding the base eccentrically to the axisof the spindle, and a doffewguard rigidly mounted on the upper end ofthe post.
